Abstract

The invention discloses a seat belt retractor, a seat belt device applying the same and a vehicle. The seat belt retractor comprises a reel, a locking wheel and a belt sensing drive device. The locking wheel is connected to a first end of the reel, synchronously rotates along with the reel when the pull-out acceleration of a seat belt is normal, and rotates relative to the reel when the pull-out acceleration of the seat belt is abnormal. The belt sensing drive device is matched with the locking wheel to brake the locking wheel when the pull-out acceleration of the seat belt is abnormal. According to the seat belt retractor, by the aid of the belt sensing drive device for controlling rotation and brake of the locking wheel, the reel is locked when the pull-out acceleration of the seat belt is abnormal, the reel cannot be locked when the seat belt is drawn into the tail end, so that 'end locking' is avoided on the premise of ensuring normal functions of the seat belt retractor, and practicability of the seat belt retractor is further improved.

Description

Technical field [0001] The invention relates to the field of automobiles, in particular to a seat belt retractor and a seat belt device and a vehicle using the seat belt retractor. Background technique [0002] The seat belt device is one of the important protection devices in the vehicle. In the case of a vehicle collision or sudden braking, the seat belt device can restrain the occupants and prevent the occupants from bouncing off the seat. The seat belt retractor is the most important part of the seat belt device. [0003] When the spool of the seat belt retractor rotates around the direction of the seat belt rewinding, especially at the end of the seat belt rewinding process, because the seat belt suddenly stops after fast rewinding, the centrifugal quality of the sensitive mechanism of the seat belt retractor The block deflects due to inertia, triggering the seat belt locking mechanism to lock the reel, commonly known as "end lock". At this time, the seat belt cannot be pull...
